New submission from STINNER Victor:
os.read() currently uses the int type for the size parameter, whereas the C
function uses a C size_t parameter:
ssize_t read(int fd, void *buf, size_t count);
The Python function must use the Py_ssize_t type, but truncate to INT_MAX on
Windows, as done in FileIO.read(). It would help to implement FileIO in pure
Python: issue #21859.
I don't think that this enhancement should be backported to Python 2.7 nor
Python 3.4.
